2 Weather-critical Applications Offshore wind farms and increasingly large solar parks play an important role in global energy supply. Our mobility knows no bounds. We rely on an infrastructure that functions efficiently - on land, in water or in the air. Experienced decision-makers ensure that outdoor technology operates flawlessly. Environmental sensors are indispensable here as the basis for decisions. 2 // Lufft WCO

3 Application Questions Can the plane land safely, even in tropical rainfall and winter conditions? Is the travel time for my route calculated correctly as a function of the weather conditions? Are there alternatives that are not restricted by the weather? Can I continue to operate the wind turbine under the prevailing wind conditions? Is the position of the turbine optimally aligned? Does my solar farm deliver the expected (energy) yield? Does my plant protection strategy work and does it prevent attack by insects or fungi? Is the air quality below the technically permissible maximum values? What long-term trends do we observe in nitrogen oxides and particulate matter in a region or city? Can large public buildings and industrial buildings be managed more efficiently, resulting in energy savings? Can snow-making equipment be optimally controlled so that there is still enough snow for tourism? Will ceilometers be able to recognize the type of cloud automatically in the future? Will a Smart Home be able to operate autonomously and energy efficiently in the future, according to the user s individual needs? Smart sensor technology for better solutions. Lufft WCO // 3

4 Metrology Sustainability ity Your systems are complex and must have a long service life. We also specified these requirements for our environmental sensors: > High long-term stability of the sensor > Very long service life > Extreme robustness > Precise measurements > Calibration capability of the sensor > Reliable measurement even under extreme conditions > Software upgrades 4 // Lufft WCO

5 You take the decisions we supply the measurement data that you need for this purpose. We deal with the measurement of all environmental data. Smart sensors allow not only reliable measurement with state-of-the-art technology, but also computing and diagnostic functions. In addition, via the serial interfaces of the smart sensor, the information can also be forwarded for subsequent processing in various languages (protocols). Whether cloud, datalogger or smart communicator. Smart sensors facilitate streamlined hardware architecture in the entire measurement setup. Applications > Proactive runway management Safe winter roads with optimal salt application > Automatic spreading > Environmentally friendly agricultural applications > Efficient plant control for renewable energies > Production of artificial snow > Energy efficient buildings System Concept Individual sensors or modulardesigned all-in-one sensors supply data via an open interface for further processing. Whether GPRS, LAN, WLAN or satellite transmission, the necessary infrastructure to provide real-time data for decision-making is available worldwide. Reliable Measurement Data Big Data provides ever increasing amounts of environmental data. Which sources can you use for decision-making? Which data can you trust? To answer these questions, in the future every measurement network needs to contain several reference stations, which measure correctly at all times. Guaranteed. We help you to master complex weather conditions. Lufft WCO // 5

7 Reliable Measurement Data Verification and Calibration What type of maintenance do you want for your environmental sensors? Reactive (in case of faults) with regular maintenance intervals? Or proactive with timely replacement of critical components? Predictive, taking account of probabilities of failure? Or availability-based, i.e. you expect data delivery, for example, in 99.5% of all possible cases? On this basis, verification and calibration activities can be performed on your measuring systems. Calibration (traceability) Environmental sensors can be laboratory tested, including traceability. In the best case, the characteristic curve of the sensor can also be corrected (adjustment). And the date of the next verification can then be set. Verification The measurement point is compared with a reference. Ideally, not only at a given time, but over a period of about one hour. A decision can then be taken regarding adjustment or replacement. Reference Sensor WS3000 > Exchangeable sensors > Redundant air pressure sensor > Excellent ventilation > Metal housing Characteristic Curve of a Wind Sensor > Target / actual comparison over the entire measuring range > Optimization of measurement accuracy by storing the characteristic curve in the sensor > Secondary calibration by the user during use Meteorology and Metrology: > Verification of accuracy, e.g. air pressure, traceable to primary standards (NIST, DAkkS, etc.). Trust the measurement data whose origin you know. Lufft WCO // 7

10 Tr a f fi cwea t her Safe Arrival Black-ice early warning systems help you to operate a proactive winter service and keep critical microclimates such as bridges constantly in view. Mobile and stationary measuring technology gives you information at any time - not only about individual measuring points, but also about the road conditions throughout your entire road network. Traffic Management Systems (TMS) require real-time information, not only about road conditions but also about wind conditions (on bridges) as well as visibility, in order to display the optimum speed in each case via variable warning signs. 10 // Lufft WCO

11 Water film height is measured in micrometers. From as little as 10 micrometers, a road is no longer dry. With more than 700 micrometers (0.7 mm), there is a risk of aquaplaning. A single measurement point is often not representative of the actual road condition. Optical, non-contact methods sample a representative surface area instead of a point. They also measure up to 100 times per second, while the measuring vehicle is in motion. The grip depends on the tire, the asphalt and the water / snow / ice layer. This weather-related intermediate layer is the key factor as far as friction is concerned. Lufft WCO // 11

12 Snow Depth Laser- Technology Clearing and spreading or just spreading? What is the cost to the municipality for the subcontractor to carry out winter maintenance? It is important to know the precise snow depths. Due to climate changes, weather experts no longer expect snowfalls to be regular, but rather heavier. 12 // Lufft WCO

13 Despite long-term warming, snowfall intensity is actually increasing. Snow depth measurements are an integral part of meteorological measuring networks. Winter services and ski regions need precise information on snow depth, whether for slope preparation or proactive clearing. In most cases, the point measurement with a single laser is sufficient. Independent of temperature, wind and relative humidity, the measurement result is highly accurate in all conditions. The measurement method of the SHM31 is based on a combination of phase comparison and time of flight. The platform-independent UMB-Config tool enables the parameterization of the sensor according to the individual requirements. The point or surface area measurement for a winter without surprises.

14 Airport Weather Safe Landing With regard to landing safety, pilots and technical airport management communicate via the so-called RCC (runway condition code). This RCC must be known over the entire length of the runway. Today s experience-based process can be supported by modern measurement technology. In this way, the exchanged information is clearly documented and traceable. > MARWIS does not record the conditions at a single point, but over the entire length of the runway > Built-in sensors measure the current runway conditions > Atmospheric sensors are used to permanently adjust the short-term forecast > Active built-in sensors determine the actual freezing temperature for each de-icing agent. This means that you remain on the safe side and can act in good time. > All measurement data are automatically transferred to the RCC messages (runway condition code) 14 // Lufft WCO

15 The ultimate secret is the friction on the runway, an experienced airport manager told us. With a combination of mobile and stationary sensors, the secret can be revealed. It is ideal to record the conditions on the entire runway, in terms of both length and width. Mobile sensors such as MARWIS can do this by installing several sensors on a unit behind the measuring vehicle. I m only interested in the weather inside my airport fence. The use of de-icing agents is expensive. For optimum proactive application, real-time data is required in conjunction with an accurate short-term prediction (Nowcast). Most accidents occur during landing and takeoff. The main reason for this is critical weather. Trust your experience in conjunction with state-of-the-art measuring technology. Lufft WCO // 15

16 Visibility VS2k/VS20k > Measuring range up to 20 km > Active defense against spiders > Contamination detection > Anodized housing 16 // Lufft WCO

17 Saturated air, fine dust and sand cloud the atmosphere and lead to reduced visibility. Meteorological networks and airport applications require a large measuring range. If the VS20k returns the maximum measurement value, the visibility can be identified as clear. Fog is caused by large temperature differences between day and night and is a micro-climatic event. Verification in the field is carried out using a calibration disc. As a further control point, the zero point is checked ( in the dark ). The degree of contamination of the sensor is transmitted together with the measured values and serves to alert proactive maintenance. In future, spiders will have to find another place for their webs. Lufft WCO // 17

19 Ceilometers help to investigate the impact of climate change. These findings are incorporated into future forecasting models. Equipment is required on location to check the functionality. The Lufft cloud height simulator allows ceilometers to be tested, even under a cloudless sky. Ceilometers are often of dual use for airport weather information and meteorology. The building of international monitoring networks for cloud and aerosol observation has begun. Currently, there are significant gaps worldwide. Through the complete automation of the observation networks, ceilometers will take on a very important role in the future, and the intention is also to automatically detect the cloud type. Ceilometers that are used for both airports and meteorology / climate research must provide precise measurement of all air layers. Very high cirrus clouds, e.g. over the equator, are over 10 km high. The extremely stable laser sensor produces raw data for all heights, which are converted into the different results. Signal processing by means of microprocessors is critical to the quality of the output. Cooperation with climate and meteorology researchers worldwide allows constant improvement of the data output and ensures application-specific use. Cloud and aerosol measurement for precise forecasting of air pollution. Lufft WCO // 19

20 Platforms and Variants an Modern sensor technology based on platform concepts. As a result, new variants required by our users can be developed faster. Platforms can be realized with replaceable or hardwired sensors. Different platforms allow us to meet the respective requirements in the best possible way. 20 // Lufft WCO

21 THE REFERENCE WMO-STANDARD METEO-SMART The WMO (World Meteorological Organization) places high demands on the sensors to be used. The reference class must not only meet these requirements, but exceed them. The WMO standard sensor is intended to ensure that weather observation takes place worldwide on the basis of identical principles. And though WMO accuracies are not always required, a professional environmental sensor is still needed. That s why we developed the Meteo-Smart series.

24 Wind Turbines Renewable ewa Energy Wind farms today are being built onshore (on land) and offshore (in the ocean). Turbines are becoming increasingly more powerful. It is not possible to operate a wind turbine without environmental sensors. The more accurate and reliable the wind sensor measurements, in particular, the better the yield of the system. Typical requirements on sensor technology: > Ice-free under all conditions > High long-term stability of the sensor > Very long service life > Extreme robustness > Precise measurements > Calibration capability of the sensor > Reliable measurement even in extreme conditions > Software upgrades 24 // Lufft WCO

27 Since PV systems are becoming ever larger, the accuracy of the irradiation measurement is increasingly important for the efficiency of the system. The secondary standard variants the highest accuracy class in the field - are provided for this purpose. Wind cools the temperature of the module and must therefore be included in the efficiency calculation. Precipitation leads to contamination or covering (snow). With increasing temperature, the performance of the solar module decreases. Therefore, it is important to measure the temperature of the solar module in addition to the air temperature. Many photovoltaic system providers throughout the world use our sensors. In general, MODBUS interfaces are used to transfer measurements to the PV controller. On request, we integrate manufacturerspecific protocols as a plug & play interface. Secondary standard for safe Why is the WMO standard required in such applications? Because the large measuring range is necessary for irradiation, in order to measure the actual efficiency of the PV system. And because the service life of the system is intended to be more than 10 years. This requirement also applies to the sensor technology. Which alternative sensor technologies are useful? GHI: Global irradiation on the horizontal surface GTI: Global irradiation, tilted. And thus aligned to the irradiation angle of the sun DHI: Diffuse Horizontal Irradiation Together with the WS600, these sensors are transmitted via a Modbus interface to the data acquisition unit / controller of the PV system.
